		win->SetForeground();
		win->SetFocus();

Works fine for me. Also you don't need to call LostFocus, this will be done for you.

Yes, it's working fine, thanks Smile

I tried a lot of things, but I missed this method !

You might want to use the Upp class Ptr<TopWindow> instead of the pointers. Then you don't need to worry about setting them back to NULL. Personally I'd keep them in an array of Ptrs.

I'm still new with UPP and don't know how to use this (even if I gess a little...). Is there a document explaining that, or I must study the sources ?

Do you really need to create/delete the windows when they are opened/closed? Unless you will have many of them you could just have them as members and not have to worry about it.

Sometimes, I have few simple windows, so I could effectively create them all at the begining. But sometimes I need several complex windows, so I think that it's better to create/delete to save memory...

Or you could google for 'Singleton class C++', which might do what you're looking for.

Yes, I could use a singleton. But is there a singleton base class in UPP ? For me, singleton is more especially interesting for a team of developpers, and in most cases I'm developping alone.

Anyway, if there is not yet, I think that a singleton base class would be interresting in UPP, even if it's not difficult to create one's own : no need to re-invent the wheel each time... Maybe to think for a next version Wink

Thanks for your help and advices Smile
